...Its too bad that KSEA is the default airport for FSX,since it has possibly the worst frame rates,but thats the way it is...

You can move the location of your default flight by simply starting fsx with the default Trike, select your new default starting location, select the correct time of day at that location, then start a flight. When the sim have loaded you click File->Save->Check "Save as default flight"

The location you chose will now be your new default flight location. Personally I have set my local airport as my default location, a sideeffect of doing this is that the time of day will always be my local time whenever I start up FSX
